It realized synchronous three-phase zero-current breaking based on an intelligent AC contactor only by paralleling the first-opening phase contacts with a unidirectional thyristor. The performance indexes and working reliability of the intelligent AC contactor were improved greatly.
介绍了一种高性能的智能交流接触器,其在智能交流接触器的基础上,仅在触头首开相上并联上一个单向晶闸管就实现了交流接触器的三相同步过零分断,大大提高了智能交流接触器的性能指标和运行可靠性。
